In 2011, a man named Ahn was arrested in Seoul. He was going to assassinate a South Korean activist named Park Sang-hak.

He was likely going to use one of these disguised weapons found by police:

1) A Parker ballpoint pen containing a poison needle.
2) A pen that can shoot a toxin-filled bullet.
3) A flashlight with holes in the front that can fire three bullets.

The intended victim, activist Park Sang-hak, is the son of a former spy for North Korea who fled with his family to the South. He has been working to bring democracy to North Korea and has sent millions of balloons filled with pro-democracy propaganda into the North.
